$(x-4)^2 \\ \\ x^2 - 2x \times 4 + 4^2 \\ \\ x^2 - 2x \times 4 + 16 \\ \\ x^2 - 8x + 16 \\ \\$

The final result is: x<span>² - 8x + 16</span>

At the movie theater, child admission is $5.30 and adult admission is 9.20. On Monday, four times as many adult tickets as child

AnnyKZ [126]

124 tickets sold at $9.20 = $1140.80
124÷4 =31
31 tickets sold at $5.30 = $164.30
$1140.80+$164.30=$1305.10
so so if you take the 124 tickets and divide it by 4 you get 31. The answer is 31 rickets were sold that day.

Cos(0)=square root 3/3, sin 0<0. what is the value of sin0

abruzzese [7]

Answer:

sin θ = $\frac{\sqrt{6} }{3}$

Step-by-step explanation:

Given that,

cos θ = $\frac{\sqrt{3} }{3}$

From the trigonometric functions,

cos θ = $\frac{adjacent}{hypotenus}$

⇒ adjacent = $\sqrt{3}$ , and the hypotenuse = 3

Let the opposite side be represented by x, applying the Pythagoras theorem we have;

$/hyp/^{2}$ = $/adj/^{2}$ + $/opp/^{2}$

$/3/^{2}$ = $(\sqrt{3} )^{2}$ + $x^{2}$

9 = 3 + $x^{2}$

$x^{2}$ = 9 - 3

= 6

x = $\sqrt{6}$

Thus, opposite side = $\sqrt{6}$

So that,

sin θ = $\frac{opposite}{hypotenuse}$

= $\frac{\sqrt{6} }{3}$

Therefore,

sin θ = $\frac{\sqrt{6} }{3}$

(Please use a separate piece of paper to calculate the answer for this problem.) A study to determine the sensitivity and specif

mina [271]

Answer:

$67.20\%$

Step-by-step explanation:

Given

$n =2430$ --- sample

$r = 16.72\%$ --- degeneration rate

From the findings, we have:

$p = 377$ --- tested positive

$t =561$ --- total test

Required

The positive predicted value (PPV)

This is calculated using:

$PPV=\frac{Positive}{Total}$

i.e.

$PPV = \frac{377}{561}$

$PPV = 0.6720$

Express as percentage

$PPV = 0.6720 * 100\%$

$PPV = 67.20$
